The nice thing with KiCAD is that a part is simply a symbol (schematic element) with enough parameters attached. You can specify footprints, MPN, ratings, value, etc. then store it in your approved and verified symbol library for use in all your projects. Use your R_4.7k_0603 symbol an it comes preconfigured with footprint, MPN, rating etc. Making these symbols is a lot of work but very simple.

Unfortunately there is no standard name for these parameters beyond footprint, value and some others. MPN, brand, rating etc. are not default. This hinders bigger adoption I think, and makes every project unique. This should be improved.
